Vitality score

Vitality score 46.7/100 — Partly served (model fr-v0.2).

Confidence: high.

Better served than 91 % of the 17,580 communes of a similar size.

Compare this with communes of a similar size. The score measures how well a place is served relative to its own size band, and larger communes score higher as a rule — so it reads meaningfully against another village, and misleadingly against a town.

Measured but not scored in this model: Market. See the methodology for why.

Climate

An average of 18 days a year at or above 30 °C and 48 days at or below 0 °C, over 11 complete years in 1995–2024. ^[11]

Measured at the COULOURS weather station, 11.1 km away at 228 m; the village itself is at 163 m. ^[11]

The village sits 65 m below the station, so each day's reading was shifted by 5.55 °C per km of altitude before the days were counted. Expect the result to be within about 0.68 °C. ^[11]

Muggy days — a dew point at or above 18 °C — average 2 days a summer. ^[11]

Humidity measured at COULOURS, 11.1 km away at 228 m, over 11 summers. ^[11]

That station sits 65 m above the village, so each day's humidity was shifted by 3.06 °C per km before the muggy days were counted. ^[11]

An average of 817 mm of rain a year, spread over 128 days — about 6.4 mm on a day it rains. ^[11]

Rainfall measured at CHAMPLOST, 6.7 km away at 122 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
